Nature Photonics@NaturePhotonicsOptics industryAI score3636Phys.org Optics & PhotonicsOptics industryPicksAI score6262 Programmable Photonic Chip Offers New Way to Probe Topological Properties of Optical Systems
A research team at KTH Royal Institute of Technology has demonstrated a programmable photonic chip that can emulate dissipative systems and detect and measure their topological properties. The work uses a mathematical method to simulate loss without actually losing the signal, then compares the light with a reference beam to distinguish topological scenarios from ordinary ones and detect exceptional points. The results were published in Physical Review Letters, and the same chip can be reprogrammed to test different scenarios.
Why we recommend it: The study reads out topological information in dissipative systems through reference-beam interference and tests different scenarios on the same programmable chip, providing a method for investigating robust properties under loss conditions.

OFweek Optics Network · NewsOptics industryOptics and AIPicksAI score6161 Fanchuangwei High-Transparency Optical AR Lens Project Lands in Taizhou with Total Investment of About RMB 550 Million
Shanghai Fanchuangwei Technology's high-transparency optical AR glasses lens project has settled in Huangyan, Taizhou, to be carried out in two phases by Fanke Technology (Taizhou), with total investment of about RMB 550 million. Phase one, at about RMB 150 million, plans to complete an innovation center and pilot production line by 2027. Phase two, at about RMB 400 million, targets annual output of 100 tonnes of high-purity silicon carbide optical material by 2028. Aimed at AI glasses and AR terminals, the project covers the full chain from optical materials and etching processes to optical devices.
Why we recommend it: The source gives the investment figures for both phases, production line timelines and a target of 100 tonnes of silicon carbide optical material per year, useful for gauging the pace of silicon carbide waveguide industrialization.

Optics & Photonics NewsOptics industryPicksAI score6565 Optogenetic Therapy Partially Restores Vision in Early Clinical Study
Optics & Photonics News reports that an early clinical study showed optogenetic therapy can partially restore vision in patients with severe vision loss. Most adverse events were mild to moderate, with only one transient severe event after injection that resolved within minutes. First author Jose-Alain Sahel of the University of Pittsburgh said the results show that the visual system retains the ability to process new information even in people with severe blindness.
Why we recommend it: Optogenetic therapy applies light stimulation directly to visual restoration, and the source article provides early clinical safety results that can serve as a reference for biophotonics applications
